Conjugated polymers (CPs) provide a pathway to designer materials with tunable spectroscopic, electronic, and/or magnetic properties. Molecular weight, polydispersity, and precise incorporation of structural elements in the conjugated backbone are among the important parameters that affect polymers’ physical properties. Pd-catalyzed Suzuki-Miyaura catalyst transfer polymerization (SCTP), a controlled chain-growth polymerization process, has shown promise in production of narrowly dispersed CPs with tunable structure and precise molecular weights. This presentation describes mechanism-based rational development of SCTP as a general method for the controlled preparation of CPs, and the importance of mechanistic understanding of this process for improving the effectiveness and controlled nature of the polymerization.
